LOGGING-CAR AND BUNK.

Application filed November 27,

To all who-m 0.. may concern:

Be it known that I, I-Innnnn'r C. JARVIS, a citizen of the United. States, and resident of the town of Benton, count of King, and State of ashington, have invented certain ,new and useful IIHIM'OVQIHGIH'S in Logging )ars and Banks, of which the following is a specification.

My Invention relates to logging cars and more particularly to the-construction whereby the bunks are supported.

The object of my invention is to provide an. eliicient and simple means whereby a Hat car of standard construction may be re modeled to make from it what is known in the. trade as a connector-l truck; that is, a car whieh has only a skeleton longitudinal ira me.

My invention comprises the novel features which will he herein described and then particularly pointed out in the. claims. In the aircoi'npanying drawings I have shown my invention embodied in the form of constructhe top bolster and r the means by which tioiiwhich is-now most preferred by me.

Figure 1 is a transverse section of a car taken through then-truck just forward of the bolster andjthe bunk.-

Ifig. '2 is a side view of one truck of such side view of one end of the bunk, together with these are connected.

. Figs. 4 and 5 are respectively bottom plan and end elevation of the member employed Fig. 3 is a detail as a filler blorlr, or bracket, between the bolstgr and the bunk.

. The type of car referred as aconnected truck is a type which consists'of two four-wheeled trucks, which are each sup lied with a log carryingbunk, the two truc s being fixedly connected together by means of longitudinal frame timbers which are all grouped along a narrow seetwn'extending along the center line of the can su'ch a caches been found to possess many practical advantages over an ordinary flat car. For one thing, it has no floor to be damaged by the dirt.

It has been common to cars for loading purposes, temporary wooden stakes, placed in the stake pockets in the side of the car, .or by mounting thereon steel frame bunks, which use ordinary flat are provided with stakes or checks for hold- Specification of Letters Patent.

to in the trade the center of the car,

logs or to hold trash and either by using Patented Feb. 6, 1917. 1916. Serial No. 133,604.

It has been found desirable to be able to take these llat ears and remodel them into-connccJed trucks. Asimple and practical way 01' doing this is the object of my present invention.

The type of truck he'ein shown is one which possesses a bottom )olster or support in; beam 1. having its ends ll. supported upon the truck frame. The truck frame herein shown comprises L transversely extending beam ill and long tud'inal extending trusses If. in the latter of which the axle. :IH journaled. The under bolster l is shown as supported at its ends h." springs 'lT.

Mounted upon top bolster 2. the iw'oh lslers hcing rounecled by a king pin at the point 21, which is the center of their lengt 1. These holsters have side bearings 10 and 20, respectively, which engage and preveit undue tipping of the top holster in eith r side direction. The top holster extends outward beyond these side bearings and in the usual typo oi construction. has a pocket or recess, formed in its older ends in whirl are placed two side beams of the car frame. This pocket ting surface 22, which in the usual constiuctionlies in a vertical plane. and a' ledge 23 projecting outwardly at the lower end tlu reor', thus forming arecess for the recepoion of the side in renmdeling a flat car to make a connected truck of it. I remove the entire floor and, the longitudinal beams and replace theinby beams 4, which are grouped in con tact, or in substantial contact, along the center line of the ear: upon the top suriaer of the. central portion of the top bolster. It is a iusto'mary practice to make. the outer side beams of a. car f greater depth than those .nwardly therefrom. The beams-which are located toward rest "p in the same top that which sas m a spaced 1: con:

surface of the bolster as tains the beams 4,'but they sider'able distance apart. The top surface of the beams 4 are at a ccmsid erable distance above the surface 24, which forms thetop of the holster near its ends.

In placing a bank, as 5, upon the timbers 4. this would be elevated some distance above the outer ends of th a holster. To properly support this, I employ filler blocks, or brackets 3, which connect the two and the und( 1' holster l' is the These. beams -1 rest .the superposed hunk 3.

add the strength of theholster to that of .thelmnk. This filler blot-k, when usedwith the type of ho ter just. described, is made of an "Lshape. as is elearly shown in Fig.

This filler block 3 is thus provided with two-arms, onearni 30. being proportioned to tit 'in the recess which had been provided at the 'outer ends-of the bolster for rewiring the side beams of the ear. and the arm 31; extending inwardly therefronraiul 'wsting upon the lop suriaee '24 of the holster,

Tlie'depth ol' the arm 31- is sueh as will'hrin its upper surface on the level with the top surlaee of the wooden beams 4.

it transmits the downward strain direet to the holster without depending upon the. strength of the bolts .b \'.whieh these parts are secured together. By this expedient. the bunk and the holster are bound together so as to form. in'etl'eot, ashig trussed beam ha\1- in'ggi'ent strel'igth. 'lhe, holster having a side bearing 20, which corresponds with the side bearing 10101 the lower b0ls ter, is,well

supported against excessive rocking movenient. The-beams 4 well support the eentral 'portiono'f the bank and form the connectmg frame between the two trucks. In this manner a flat cjfarjnay beeheaply remodeled into a 'conheetedtruck.

What I claim as my invention is:

1. In a lo gi'ng car, in combination, a

I day of November, 1916. bolster exten' mgjubstnntiglly the g e I W1 seat and the other arm upon the. top surface of the holster inward from said seat, and a hunk seem-ed on top of the said filler liloeks. 3. In a logging ear, in eombiuation, a holster havin beam receiving and support-- lug sun-fares in the central portion thereof and a depressed heanorm-airing pocket at earh end. a liller hloek entering eaelr of said pockets and overlapping upon the holster inward from and adjacent said pockets, longitudinal ea r beams carried upon the central part of said holster. and a hunk bearing upon said healus and tiller hloeks. -l. la a logging ear, in eomhinat-ion a holster extending sulistantiallr the width of the. ear.- an L-shaped .hloek fitting over each end of the bolster and secured thereto. and a hunk secured to'the top of said block. 5. In a logging ear, in combination, a holster extending substantially the width of the ear. an L shaped' hlork fitting over each end oi the holster and seeured thereto. and

6, In a logging ear. in combination, a lruek holster. a car holster, said bolsters centrally pivoting upon 'eaeh other and having 90 side bearing surfaces toward their outse ends, the top or car bolster extending he r vond said side bearing surfaces, a filler bloek seei'u'ed upon each end of the car bolster and having-a supporting and a thrust bearing 9 5 upon-said 'car bolster resisting" movement.

toward the center of the holster, and a. log

bunk mounted upon said filler blocks. Signed at Seattle, .VVashingto'n, this 20th HERBERT (3. JARVIS;
